+Changelog Entries
+===============================================================================
+
+The project uses `Towncrier <https://towncrier.readthedocs.io/>`_ to manage its
+changelog. When making changes that should be noted in the changelog, add a
+file ("fragment") to the ``documentation/towncrier`` directory with of
+``<issue_number>.<type>.rst``, for changes with a Github issue, or
+``+<title>.<type>.rst``, for changes without an associated issue number.
+
+The entries will be collected and organized when a release is made, as
+described in the release process sections above.
